    Computer won't boot with 2 monitors connected


    I've been having this problem for about a year now. When I built my PC, I only had one monitor and everything ran smoothly and fine but as soon as I added a second monitor there is a 50/50 chance that my PC will boot up with two monitors connected.

    When I turn my PC on it will turn on but nothing will display on both monitors and I get a white Light (CPU) error code on my Asus mobo (strix 270-e). If I want to start my PC with two monitors I have to unplug one monitor, boot up, then plug in the second monitor and everything is fine. I use DP to DP and HDMI to HDMI so I know its not the cables.

    Also, I originally had a GTX 1050ti and when I upgraded to two monitors the problem started happening. I assumed it was the GPU so I waited and then bought a GTX 1070ti a while later. Same problem is still happening so I know its not the GPU. I also tried moving the GPUs to different slots in the mobo and same problem so the slots are fine as well.

    I have tried Uninstalling and reinstalling windows and reverting to default on my BIOS settings and nothing happens. I have also tried configuring multi displays in the BIOS and that didn't do anything either.

    Any suggestions? Thanks for the help in advance.

    :)

    i have a problem to connect 2 monitors.

    Hi Ron,

    Thank you for posting your query in Microsoft Community.

    • What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
    • How are you connecting to the 2nd monitor?
    I suggest you to follow the steps from this article below:

    [Applies to Windows 10 as well]

    Regards.

    computer won't boot but has power

    Kursah, that 6 steps are granted it always boots at the 6th step (sometimes at the 4th) and I have to remove the ethernet cable every time otherwise I'll have to do countless steps, that's a fact. I do not have Wake On Lan set.
